Executive Summary

We are developing a laser-driven experimental platform to reliably and repeatably generate ejecta, which are discreet, high-velocity, solid-density bits of material. The interaction of ejecta with solid barriers and with other particles is a long-standing computational and experimental challenge relevant to hypervelocity impacts of space dust with satellites and to our understanding of the function of nuclear weapons components.
